Description of key information

The viscosity range of IOA at 20.0 °C is 1.88 to 1.98 mPa∙s.

Key value for chemical safety assessment

Additional information

The viscosity of IOA was measured at three temperatures using two different samples of test substance. Measurements were made with a Cambridge Model 4000 viscometer which was calibrated against Cannon Viscosity Standard Fluid S20. The instrument used in this study was a calibrated oscillating piston viscometer. Although the viscometer is compliant with ASTM D-7483-08, and company specifications indicate correlation to ASTM D445 standards, it is unknown if this study followed an ISO, ASTM, or OECD guideline, as well as whether the study was conducted in accord with GLP guidelines.
